Huge numbers of retards build ARs and tons of videos have a lot of ridiculous misinformation

dont do it, you'll just somehow manage to anneal your barrel

Arfcom tuning guide has people laying shims around the barrel to make it tighter. That would be wack

That’s common

Feeling around again, there actually isn't a noticeable bur. It looked like there was one though.

just take it to the fucking gunsmith

I've never had an extension that loose

What parts did you buy?

This dude really earning his blue name

Nor have I but I know people will do it just to make it jam packed tight

Faxon Gunner barrel, Aero milspec upper.

yeah i assure you there is no problem with the parts

They're both probably right

i trust both faxon and aero a lot more than i trust you

Yeah both of those are fine

Those companies will have go/no go gauges in production and qc

You should really reassess building your own AR before you lose an eye to a detent and spring

Well that's a relief. I've been counting the hours to the barrel getting delivered.

wait

you dont have the barrel?

🤔

@5W upper and lower are already assembled but ok.

How is it assembled if the barrel is not in it

@glacial pace yes I do. I just got it. I've been waiting and didn't want to have to return something.

Just knock off the burr, use some decent grease if not aeroshell, wiggle it in carefully instead of hamfisting

@5W ok well the parts kits are assembled.

trying to assemble an upper without barrel nut grease is like trying to do your brakes without brake fluid on hand

you cannot accurately torque your barrel nut without it and there will be nothing preventing the steel from seizing to the aluminum

And then skip forward to the part where you fuck up torquing the nut

Bro my engine doesn’t need oil yet I just wanna make sure everything runs correctly first before I waste 11 dollars

yea im just gonna put the oil filter on to see if it works haha

I’m looking forward to the part where he goes to his first range trip and the gun is either horribly inaccurate or unreliable and he tries to blame the parts

or the classic castle nut walks off

Faxon and aero are meme brands

Literally everything I've seen shows them having plenty of wiggle room to do it without grease.

you are missing the point

You're on the tight side of tolerance, congrats that's a good thing. Lube it up

the grease isnt essential for ease of handling, its essential for other reasons, it just happens to help with fitting

Damn dude

You’ve been watching some dipshit on YouTube filming in his dim house with a mattress on the floor in the background as he mumbles into the camera and fumbles with parts one handed

you are torquing a (likely) steel barrel nut onto an aluminum thread
